. 1 Claim. 1

This invention 'relatesto new and useful improvements shipping containers generally and particularly seeks to provide anovel boxsuitable for the packaging of bottled goods and fabricated of corrugated board'or the like, in which reinforcingmeans are provided for the ends and side walls.

An object of this invention is to provide a shipping container ofthe-character stated which may be constructed from. a single .cut and scored blank of corrugated orotherpaper board without any additional elements.

Another object of this invention is to provide a shipping carton of the characterstated in which the end walls are composed of three plies, provided withhandholes, and the upper inside portions of such-end walls above the-handholes togetherwith the side walls are provided with reinforcements formed from extensions of theend walls so that stresses imposed on a filled container when it *is'lifted'may be-more readily withstoodi Another object .of thisinivention is toprovide a shipping carton of the character described in which the side walls are reinforced at the upper inner portions so that the stresses imposed on filled containers during packing and storing in vertical series may be more readily withstood.

Another object of this invention is to provide a shipping carton of the character stated which includes a bottom, side walls, end closure flaps carried by the side walls and bottom to form a triple-ply end closure, a pair of top closure flaps carried by said side walls, and a pair of reinforcing flaps carried by opposed respective end closure fla s, said reinforcing fiaps being adapted to be rigidly affixed to the entire upper inner edge of the carton.

With these and other objects in View, the nature of which will be more apparent, the invention will be more fully understood by reference to the drawings, the accompanying detailed description, and the appended claim.

In the drawings,

Fig. 1 is a perspective view of an erected container constructed in accordance with this invention;

Fig. 2 is an enlarged horizontal section of one corner taken along line 22 of Fig. 1;

Fig. 3 is an enlarged vertical section of one end ta en along line 3-3 of Fig. l; and

Fig. 4 is a plan view of a blank from which the container may be formed. I

Referring to the drawings in detail, the invention as illustrated is embodied in a shipping container so constr uctecl and proportioned as to be particularly suitable for use as a container for shipping bottled goods The container can be initially formed from a singlecut blank generally designated at 5 0f corrugated-board or the like which "includes a bottom- 5- and side walls "1. Thebottom carriesan outer end panel 8 at -eaoh--end, provided witha die-cut handhole flap-9 fold'able' about score line It, disposed'parallel to the upper end and spaced nearer the top of the associated outer end panel 8. Each-outer end panel also carries a relatively long-narrow reinforcing st-rip generally indicated at 1 I and divided intothree panels -by scorelines l2, l2, a central'portion l3 being coextensive in lengthwith the widthof' outerend panel 8 and the 'endportions 14, I4 each extending'a distance equal to one-halfof the sidewall 'l. Eachside wall carries an end panel 15 at-each end; said end-panels each havinga cut-out handhole I 6* positioned so'that it will overlie the handhole of the outer panel Bafterthe boards-formed and sized slightly larger so as to accommodate the handhole flap 9 when it is folded throughthe combined aligned handholes as shown in Figs. 1 and 3. Each side wall also carries a top closure flap I 1 which is provided with an inner flange [8.

By referring to Fig. 1 of the drawings it will be observed that a carton constructed in accordance with this invention when erected has the bottom 6, side walls 1 and triple-ply ends 8, l5, l5 so arranged to define a generally rectangular body, said triple-ply ends being stapled, glued or fastened by other means to retain the shape of the carton. The end portions M of the reinforcing strip H are folded at right angles at I! and the entire strip folded inward and downward until the central portion I3 is in juxtaposition with the upper portion of the associated end wall and the end portions I4, 14 are in juxtaposition with the upper portions of the associated side walls, each said end portion reaching the midpoint of the upper edge of the respective side wall. The reinforcing strip at the opposing end is folded in the same manner, said end portions I4 reaching the midpoint of the upper edge of the respective side wall, thus making a complete reinforcing strip around the entire upper edge of the carton. Said strip may be stapled, as at l9, glued or fastened by other means. Said means of fastening the strip may be, if desired, the sole means of retaining the shape of the carton.

When a carton is being formed it is preferable to have the outer end panel carry the handhole flap B and the reinforcing strip ll. Thus when the reinforcing strip is folded over into juxtaposition with the innermost end panel the strip will serve as a binder to hold the three end panels together and will also distribute any stress among the three end panels and the reinforcing strip. Also, when the handhole flap 9 is folded in through the series of handholes and then up, said handhole flap will serve to make a smoother receiving support for a hand and will also distribute the stress caused by carrying the container to the three end panels and the reinforcing flap.

The top closure flaps l1 remain free to be opened or closed. The inner flanges l8 provided thereon are folded inwardly so that they are out of the plane of the closure flap and generally the two inner flanges will be at right angles to the closure flaps and superposed against each other when the top closures are folded down to the closing position. The inner flanges give an added strength to the edges of the closure flaps where they are attached and also tend to keep the closures from opening while the carton is being handled. It will be noted that the top closure flaps I"! are slightly longer than the respective side walls so that when closed the closure flaps rest on the full top surface of the end walls. Therefore, the inner flanges l8 are shortened slightly at each end in order to move freely inside the container when being closed.

Many efforts have heretofore been made to provide shipping cartons adaptable for the packaging of bottled goods in which the entire wall areas are reinforced. These reinforcements have invariably been created at materially greater cost of assembly, compelled the use of a greater amount of paper board from which the container has been fabricated, and required a plurality of cut blanks to form the carton. It is a feature of the container of this invention that it can be fabricated from a single cut blank of container board. At the same time top closure flaps are provided with inner flanges, all from the same single cut blank so as to provide a closure which is stronger and will not tend to open on handling.

It is, of course, to be understood that various details of arrangements and proportions of parts may be modified within the scope of the appended claim.

I claim:

A container formed from a single cut blank of corrugated board and comprising a bottom, side and end Walls and a top closure, said end walls each being three-ply and provided with a handhole located near the top edge thereof, a relatively long and narrow reinforcing flap being carried by and extending across the inner face of the associated end wall in the area between the top of said end wall and the upper edge of said handhole and being provided with extensions projecting from each corner along the inner faces of said side walls for a distance substantially equal to one-half the length of said side walls, and means for rigidly securing said reinforcing flap and its extensions to said walls whereby to provide a reinforcement extending completely around the container adjacent the upper marginal edge portions of said walls, said top closure being formed by a pair of closure flaps formed integrally with said side walls and each closure flap having an inner flange in a substantially different plane than said closure flap.
